How much torque can a human generate with a screw driver?

Torque screwdrivers can exert torques from 0.04 N⋅m to at least 27 N⋅m. Although no single tool covers the entire range, low-, mid-, and high-torque ranges are available. Torque screwdrivers and torque wrenches have similar purposes and mechanisms.

How hard can humans squeeze?

Grip strength is typically measured in pounds, kilograms, or Newtons by squeezing a type of muscle strength testing equipment, known as a dynamometer, about three times in each hand.

How many humans does it take to make 1 horsepower?
